' vantages often met with in apparatus of this kind as heretofore constructed The invention consistsinthe novel construction, arrangement and combination of parts hereinafter fully described, illusti'ated in the drawings and pointed out in the appended claims.

in the drawings: Figure 1 se ion pa embodying my invention, Figs. 2 to '4 elusive, are detail views hereinafter rred to,'Figs. 2, d, and 6 being sections, ig. 3 an elevetion, and 7 a sectional view partly in elevation. Fig. 8 is anend is a vertical elevation of Fig. i. I v 4 "The'uprights l, 1, 1 of the chamber, carrying the roof and thcflwalls, are not placed egainst the Walls of the chamber, but separated from the same by the width or an inspection passage. They can boot iron, Wood,

reinforced concrete or any other suitable substance, and carry the roof directly, .the latter being calculated so as to besuflicientlfy strongfto hold. the Weight of the covering and. the Walls of the chambers; The framework of the roof can also be made of iron, Wood or reinforced concrete, but-itvis preferably constituted by trusses of the Polonceeu type strengthened'so as to be capable o'f carryin the two loads mentioned above, and the ceiling of the chamber is more or less arched, in order properly to utilize the space and to compensate better the, effects of ex- At the right hand side of the Walls, all around the chambers and supported hythe trusses of the roof, runs a line of double angle irons 2, 2 (Figs. 1 and 2) with which engage the hoolcs 3 (Fig. 2) or U-, brackets (Fig, 3) or any other means or" suspension, to 'vvhich are suspended iron ties constituted either by, two bar irons i (Fig. 4) or angleirons 5 (Figd) providedwith holes and compressing the connection hereinufter referred-to, by means of a series of at view partly in elevationof an apbolts passing through the-holes; or by a round iron bar 6 (F1g. 55) around which is soldered the connection Which is thus secured to the tie. These ties are almost as long as the vertical height of the chamber, and are taken up at the bottom by another hook 7 'dependin on the pan. To each of these ties s secure as already-stated, a connection in a single iece, which is itself soldered -fro1n top to ottorn against the Wall. The

wall is thus held throughout the Whole of its height by this connection of a port socured to the tie which is securedto the roof byineans of a double angle iron, and atthe bottom to the pan which is provided to that 'end, with. anangle iron at the top. This angle iron 7 (Figs. 1 and 6) i is provided with holes at the points corresponding to the ties, and a hook "7 passes through each of the said holes. The hook is held in the zingle 7 iron by a nut (Fig. 6). In cases ill-Which the chamber has to Work under very heavy pressures or depressions, ,as is the case when fans are used, n order to prevent the traction or pull on the ties from exceeding a certain limit, the lower hook can he provided with a spring 8 (Fig; 6) which allows the tie to expand or contract Within suficient limits in order that the efiect's due to expansion or the slight movements of the Wallsshould be possible.

.The pan ismad'e of sheet iron or steel,

cool, and consequently to avoid the premature Wearing out-mentioned before; the bot tom angle of the pan'is roundedofi', and the bottom return is sufficiently longin order that'the 1 5 centimetersof lead at the bot{ tom which is generally corroded, should be properly cooled and consequently attacked Less. The floor oi the passageis arranged so that a current of air may be produced a fiend constantly cools the pan, b I The. floor below the bottom of the lead chamber may be of wood as usual 10, (Fig. l) or, if it is desired that the chamber should be absolutely noncomlnistible, it can be made of reinforced concrete 11 (Fig. l in that case the reinforced concrete is provided. with holes arranged hiirly close together and connected togethenhy small grooves in ,oi'dcrthat an? leek in the botsuitable numberof holes.

The ceiling, as already stated, is preferthe action of cement on thelead. 'It can also be made of sheetme'tal provided with a ably arched in order that the expansion should not open the walls but simplyraise the ceiling. The connections are also constructed for the purpose. To that end the connections areof very small height and against the lead connection; iron wires 18, 13 (Figs. 1 and 7) take up the connecvt'ions from place to place, and transmit the load to the angle irons or wooden parts supported by the trusses of the framework. It the ceiling is entirely of reinforced cement, these iron wires can be'sealed in the reinforced cement directly.- Two or more chambers can be arranged side by side, and

' may be of horizontal, rectangular, circular,

.cular, square or rectangular cross-section continuous-verticalconnections 14, 14 (Fig. ,8): secure the lead to iron ties supported at thetop by the roof or the special frame-- work of the. towers, -the uprights of which oyal or any other desired cross section.

Glover and Gay-Lnssac towers with circan be built in the sameway. A series of are however at a distance from-the walls, so as to allow free circulation of air and to facilitate repairs. It is unnecessary in that case to take up the ties at the bottom,as pressure effects are felt very little on the towers. I

What I claim as my invention and desire to secure by Letters Patentis -1. In an apparatus for the manufacture of sulfuric acid the combination with a framework, of roof trusses supported thereby, a lead chamber comprising a ceiling and sides and a pan forming the bottom of said chamber, double angle-irons extending around the said chamber and supported by the said trusses, tie-bars approximating in length the height of the chamber, an angle-- iron'carried by the pan at its top, connections between the upper end Jf the t e-bars and the angle-irons carriei by-the roof trusses and between the lower end of the tiebars and the angle-iron carried by the pan,

and connections between the ceiling and the roof trusses.

2.1'n an apparatus for the manufacture of; sulfuric acid the combination with a framework, of roof trusses supported thereby. a lead chamber comprising a ceiling and sides and a pan forming the bottom 'of said chamber, double angle-irons extending around the said chamber and supported by 'the said trusses, tie-bars approximating in length the height ofthe chamber, an angle- Tron carried by the pan at its top, connections between .the upper end of the tie-bars and the angle-irons carried by the roof trusses and yielding connections between the lower end of the tie-bars and the angle-iron on the pan.

3. In an apparatus for the manufacture of sulfuric acid the combination with a framework, of roof trusses supported thereby, a lead chamber'comprising a ceiling and sides and a pan forming the bottom of said chamber, double angle-irons extending around the said chamber and supported by the said trusses, tie-bars approxnnating in length the height. of thechamber, an angle- 1ron carried by the pan at its top, connections-between the upper end of the tie-bars and the angle-irons carried by the roof trusses and between the lower end of the tie barsand the angle-iron carried by the pan, and connections between the ceiling and the roof trusses comprising ad jacently-arranged bars, a conuection bolted between said bars and carried by the ceiling and wires suspending said adjacently-arranged bars from the roof trusses.

4. In an apparatus for the manufacture of sulfuric acid the combination with a the' tie-bars and the pan, and" connections between the ceiling and the roof trusses.

5. In an apparatus as described the combina'tion with "a floorand a framework supported. thereby, of roof trusses supported by the framework, a lead chamber comprising a ceiling and sides and a pan forming the bot-t'om of the chamber,-tie-bars secured to tie sides of the chamber, connections between the upper end of said bars and the roof trusses, and between the lower end of said bars and the pan, and means provided in the floor whereby air currents may cool the pan and leaks therein be detected.

In testimony. whereof I have signed my name to this specification in the presence of two subscribing witnesses.
